Potatoes tend to become waterlogged when you freeze them, which can render frozen sweet potato fries soggy and limp when you cook them. However, additional ingredients and certain pre-cooking techniques help preserve the sweet spuds' texture, whether you oven-bake or pan-fry them.
Store sweet potato fries at or below 0 degrees Fahrenheit. Leave space around the bags when you first place them in the freezer so that the cold air can circulate around them, freezing the fries quickly. Stack the bags close together once the fries are frozen solid. Use frozen fries within 12 months for the best results.
